SASH-FASTENER.

SPECIFICATION forming part of Letters Patent No. 739,410, dated September 22, 1903.

Y Application filed March 15,1902. Serial No. 98.366. (No model.)

T all whom r maypcOn/c'ern:

Be it known that we, GUSTAV GOERK, residing at Newark, and JACOB GOERK, residing at Irvington, in the county of Essex, State on, which form part of this specification.

The objects of this invention are to enable a sash to be locked automatically when the window is closed', to enable the locking to be eected with greater nsecurity against outside manipulation, to provide a device that is co mpact and neat in appearance and of small cost of construction, and to 4secure other advantages and results, some of which may be referred to hereinafter in connection with the description of the Working parts.

The invention consists in the improved sash-fastener and locking device and in the arrangements and combinations of parts of the same, all substantially as will be hereinafter set forth and nally embraced in the clauses of the claim. l

Referring to the accompanying drawings, in which like letters of reference indicate corresponding parts in veach of the several figures, Figure l isa perspective view of the fastener applied to the portion of a windowsash, the same being shown in locked posi-j tion. Fig. 2`is a view showing the parts when the window is open. Fig.3 is a sectionalde tail of the uppersash member. Fig. 4 is a sectional detailshowing the lower sash memff, between which is pivoted on the pivot g a locking-lever h, of peculiar construction, the said pivot gbeing provided with acoilspring vl, bearing at one extremity upon the lever h and at the other extremity upon the frame or plate e or one of the ears thereof. The said lever h is provided at one end with a linger-piece j, which projectsaway from the pivot and ears fa distance sufficient to enable it to overlie the member d, so that when ger piece of the lever is raisedv or turned.

toward V"che position shown in Fig. 3 projects out to engage the bearing o of the catch member d, for a purpose hereinafter def` scribed. When the sash is drawn down, the said member d engages at the bearing o a locking-lever m to release the same from the lip or catch lo, so that the spring i may oper- -ate to throw the leverj to its locked position over the member d. The locking-lever m is .pivoted upon a pin n, attached to one of the ears of the plate e, and projects forward into the path of the bearing o, so as to be pressed down when the lower sash b is closed. The said leverm is provided on'its upper side with one `or more teeth or catching-bearings 7o to engage the lip or catch k, and when the said lever mis pressed down, as described, the lip or catch lo will be disengaged from the tooth la', as will be obvious upon examination of Fig. 3. The said lever m is furnished wi-th a coil-spring p, which is arranged on the fulcrum-pin n and has its ends engaged to the plate e and lever m, bearing upon the said lever m, so as to throw it automatically upwarll into its catching relation to the said lip .f v

The parts being in the open relation shown in Figs. 2 and 3, upon closing down the lower v ICO' sash the bearing o first engages the projecting lever 'm and releases the same from the locking-lever 77 and the latter turns under the power of the springt', so that the upward projection o2 of the member d enters the recess h3 of the lever to prevent the lower sash from being raised. Manipulation of the lever h from the outside by means of inserting a knife or the like between the sashes is obstructed by the lever in, projecting across the p lane of meeting of the two members c d, and is further prevented by locating said plane of meeting of the members a little to one side of the plane of meeting of the sashes. To

open the lower sash, the locking-lever 7L isl raised by its finger-piecej up from the member d and automatically held in its raised position by the teeth of the catching-lever m, engaging the lip la on the rear end of the locking-lever. Obviously before the catchlever m can raise to engage said lip k the sash member d of the fastener must have been lifted sufficiently to disengage its bearings 0 therefrom, and to effect this the throw-arm l of the locking-lever engages the bearing o of the lower sash member b as the locking-lever is swung open and forcibly raises the lower sash member d a little, so that the catch in is free to act as described. It is sometimes desirable, as in washing the Windows o1' the like, to hold the locking-lever h permanently inoperative, and to this end we have provided the catch member c on the outside of one of the earsf thereof with a normally open spring -q, either fiat, coiled, or otherwise, having at its free end a pintle o, which enters a perforation in the said ear and engages the lever]l at a point eccentric to the shaft g to prevent turning. When it is desired to hold the lever in its position as shown in Fig. 3, it becomes only necessary to turn the lever 7L to its open position and press the spring q and pintle 9*, so that the latter enters into engagement with the back of the throwing-arm Z to hold the lever in open position, the pressure of said arm against the pintle causing friction enough to overcome the tendency of the spring q to throw said pintle outward. Obviously under these conditions the sashes may be run up or down with the utmost freedom and withv no danger of locking them, although the lower sash cannot be closed entirely down to the sill because of the engagement of the shoulder 0 of its member with the lug 7c of the locking-lever. The crack thus left open, however, is not more than an eighth or a quarter of an inch and is immaterial under the circumstances when it exists.

The catch-lever m is preferably provided with a series of ratchet-teeth 7c lo 7a to insure an automatic catching should one of the teeth fail to perform its duties or to secure a cer; tain catch under dierent adjustments of parts. The catch or fastener thus described is particularly desirable in connection with windows having meeting-rails that are not conveniently accessible, and in this event the lever j may be provided with a cord or other connection arranged over a pulley and adapted to be easily grasped by the hand and pulled to open position.

We are aware that various modifications may be made without departing from the spirit and scope of this invention, and consequently we do not wish to be limited by the positive descriptive terms employed, excepting as the state of the art may require.

Having thus described the invention, what we claim as new is- 1. In a sash-fastener, an upper sash member having a locking-lever provided with a catching-lip, acatchingdeveradjacent to said locking-lever and adapted to engage the said lip thereof to hold the locking-lever in unlocked position, a spring normally holding said catching-lever in such engagement with the lip of the locking-lever, a lower sash member adapted to engage said catching-lever and release the same as the sashes are closed, and auxiliary means for holding the locking-lever inoperative independent of the said lever and catching-lever and lower sash member.

2. In a sash-fastener, the combination ,of

two cooperating members,a locking-lever having at its rear extremity a catching-1ip,a 95

catching-lever pivoted beneath said lockinglever to engage said lip and projecting at its forward end to be engaged and released by the other sash member, and a throwing-arm upon said locking-lever adapted to raise the lower sash as the locking-lever is turned into idle position.

3. In a sash-lock, the combination with a sash member presenting upwardly-projecting parallel ears, a locking-lever pivoted between said ears and having at its rear end a catching-lip and a throwing-arm, of a catching-lever adapted to engage said lip, a cooperating sash member having bearing-surfaces for the said catching-lever and throwing-arm, and a slidable pin working through that ear adjacent to the throwing-arm and adapted to engage the rear edge of the latter as a stop.

In testimony that we claim the foregoing we have hereunto set our hands this 28th day of February, 1902.

GUSTAV GOERK. JACOB GOERK.
